bug base?
As The Linux community has been known from the 'direct attack'-mode againsta Micro$soft it should be good for Micro$oft to take the same attack on itself...

it's laying itself an trap.. if the Server Proves To be as bad of an bugbase as Windows95/98 has proven to be, or even has bugs Like apache has had... it will mean BIG security bugs in Microsofts softwares.. and as every Linux user knows, "you have to get patches to fix 'em"..
-> Service Packs will grow out of control.. (as they have now in NT)
-> patches will be TOO late.. (week is nothing, month can be tolerated, but 1-6 months)

as soon as the hysteria will move on to Windows users.. either the server isn't used, which is the good case on Microsoft.. or people are moving to other OS's.. or just refuse to buy W2000...
